Aberrant migration by Toxocara pteropodis in flying-foxes--two case reports.

Adults of the large nematode, Toxocara pteropodis, have not previously been reported from extra-intestinal sites in their hosts, juvenile flying-foxes (fruit-bats of the genus Pteropus). In one captive bat which died unexpectedly, a nematode was found coiled within the gall bladder and common bile duct; in another a nematode was in the esophagus and protruded into the laryngopharynx. Like other ascaridoids, this species is capable of aberrant migration.
